In Good Faith, we used your company Kulacz & Sons Heating & Cooling we are not satisfied with…read morecertain things that have happened. For example, having the air conditioning and heat going on at the same time would eventually cause risk of wear and tear the heating & air condition, causing us to have a new unit installed, being professionals that should have never happened. Also, when taking out the old furnace, you used no covering and left pieces of stuff everywhere that they didn't clean up and a mark on my wall that will not come out. Perhaps if the worker concentrated and spent more time on the job rather than being unprofessional, installing the furnace job would have been done correctly in the first place. Approximately we have spent roughly $11,600.00. It's unnecessary getting the service done from this company in the future. We would not recommend this company to anyone.

I would give zero stars but that is not an option. Dykstra sold to precision and they are not an…read morehonest company. My a/c went out and their service tech came to my house. After looking at the unit, Caleb, the service tech, told me I need to replace the whole system abd it would be 28k for a new furnace and a/c. Luckily I called for a second estimate. M & B inspected the unit and replaced the controller. The parts and labor were $350.00. If precision gives you an estimate, get a second opinion. They did however refund the price of the service call.

I Google heating and cooling places by me and Dykstra came right up with 4.5 stars. I made the call. Within 2 hours Zack shows up. Very kind and professional!! 6 stars for Zack - he diagnosed the issue right away and explained everything. I'm only giving 4 stars overall because I couldn't get the unit installed same day or even next day. Wednesday Ray and Victor installed the new unit. Nice guys. Thursday I get home and its freezing in my house. I notice that the thermostat reads 64 but set to 70. I call Zack, my saving grace!! He calls the office and they send Casey (sp?). Casey showed up that afternoon and found that a wire had shorted. Quick fix and he was on his way. I do recommend Dykstra. There is some confusion with the answering service and a merge going on, but I was able to talk to someone that knew what was going on.

My water heater went out unexpectedly, a water heater another plumber told me only 2 months ago…read moremight need to be replaced in the future but I had at least a couple of years left on it. I began shopping around for quotes, and was ignored or - in one case - told they wouldn't work on it "but good luck". We have an older manufactured home that we're trying to keep alive just long enough to build our forever home, but that still requires the occasional repair and all we seem to run into are people who tell us it cannot be done. Our house is too old. Our equipment is too old. Nothing can be repaired. Sometimes we can't even get people to show up and replace them. Then I met Alex. We discussed multiple options, and we decided to upgrade to a tankless given that the old water heater had apparently been leaking - a fact that the other plumber had apparently completely missed. Not only that, he was able to diagnose an issue with our furnace that will allow us to give it a much needed repair for far, far less than we were quoted. (Originally we were told we needed a full replacement as parts couldn't be ordered for it. He immediately found the part and it's cheap and easy to replace!) Alex treated us like people, listened to us, helped however he could, and even when parts didn't fit he worked tirelessly to get replacements immediately. He was always customer conscious. He's not only earned loyal customers for life, but we already have other jobs lined up for him. Honestly, I'm just grateful there are still people out there operating with this level of integrity.
